• Based on the minimum potential energy principal , the influences of three loads , which are concentrated force , trapezoidal load and sinusoid load , over shear lag of cantilever single - box - single - cell box girder are deducted and discussed , and a conclusion is reached , which has some instructive significance for designer to determine the sectional dimension and reinforcing bars ; the bending normal stress changes greatly as considering the shear lag effect
  以最小势能原理为基础，推导并讨论了3种形式的荷载：集中力、梯形荷载、正弦形荷载对悬臂单箱单室箱形梁剪力滞的影响，得出考虑剪力滞效应后弯曲法向应力有较大变化的结论，对设计人员确定截面尺寸、截面配筋具有一定的指导意义。
